Hydrogen gas is the most abundant element in the universe. It is a colorless, odorless, tasteless, nonflammable diatomic gas. The density of hydrogen gas at standard temperature and pressure (STP) is 0.07967 grams per liter (g/L).

Density of Hydrogen Gas at STP

The density of hydrogen gas at STP is 0.07967 grams per liter (g/L). The volume occupied by 1 mole of a substance under standard conditions is called its molar volume. In other words, it is the volume occupied by 1 mole of any substance under standard conditions.

The molar volume of hydrogen gas at STP is 22.4 liters/mole (L/mol). When calculating the density of any ideal gas at constant pressure, we use PV = nRT as an equation to determine its mass per unit volume or mass density (ρ) in SI units or slugs/ft3 in English units:

ρ = M/V = 0.7974 kg/m3.
